    "abstract": "Heisenberg-limited measurement protocols can be used to gain an increase in\nmeasurement precision over classical protocols. Such measurements can be\nimplemented using, e.g., optical Mach-Zehnder interferometers and Ramsey\nspectroscopes. We address the formal equivalence between the Mach-Zehnder\ninterferometer, the Ramsey spectroscope, and the discrete Fourier transform.\nBased on this equivalence we introduce the ``quantum Rosetta stone\u0027\u0027, and we\ndescribe a projective-measurement scheme for generating the desired\ncorrelations between the interferometric input states in order to achieve\nHeisenberg-limited sensitivity. The Rosetta stone then tells us the same method\nshould work in atom spectroscopy.",
